如何使用OmniXML删除子节点？ [英] How to delete a child node using OmniXML?

问题描述

我想删除行路径部分中带有 pathid = 2 的行...

I'd like to delete the line with pathid="2" in the rowpath section...

<?xml version="1.0" encoding="utf-8"?>
<LostPath Condition="Active" Selected="train.exe" FullPathOfSelected="D:\mygames\arcade\train\" Selected="0">
  <rowdir Name="train.exe" GamePath="D:\mygames\arcade\train\" Selected="0" />
  <rowdir Name="othelo.exe" GamePath="D:\mygames\arcade\othello\" Selected="3"/>
  <rowpath Name="train.exe" PathId="1" LevelPath="D:\mygames\arcade\train\levelpack1" levelsFound="27" />
  <rowpath Name="train.exe" PathId="2" LevelPath="D:\mygames\arcade\train\levelpack21" levelsFound="19" />
  <rowpath Name="othelo.exe" PathId="0" LevelPath="D:\mygames\arcade\othelo\levelpack1" levelsFound="11" />
</LostPath>

我该怎么做？

推荐答案

尝试使用此功能。

uses
  OmniXML, OmniXMLUtils;

procedure TForm1.Button1Click(Sender: TObject);
var
  XMLNode: IXMLNode;
  XMLDocument: IXMLDocument;
begin
  XMLDocument := CreateXMLDoc;
  if XMLLoadFromFile(XMLDocument, 'XMLFile.xml') then
  begin
    XMLNode := XMLDocument.SelectSingleNode('/LostPath');
    DeleteNode(XMLNode, 'rowpath[@PathId="2"]');
    XMLDocument.Save('XMLFile.xml');
  end;
end;
